bonding: use rcu_dereference() to access curr_active_slave

The bond_info_show_master already in RCU read-side critical section,
and the we access curr_active_slave without the curr_slave_lock, we
could not sure whether the curr_active_slave will be changed during
the processing, so use RCU to protected the pointer.
